Up until now, the closest Jerry Seinfeld has come to being a late night host was during season three of Louie (okay, and maybe The Tonight Show, but everyone was rumored for that at some point). But that all changed Friday night, when Seinfeld took charge of Late Show with David Letterman and gave Letterman a piece of his own medicine by grilling him from the host's seat. "How am I possibly going to be entertaining with this giant looming to my left?" Letterman mused. "With a bad attitude, also!" Seinfeld chimed in.
Letterman expressed much admiration for Seinfeld's Comedians In Cars Getting Coffee web series ("[It's] genius, because you can do it for next two years, or next 10 years, it doesn't make a difference"), but Seinfeld needles him about "quitting" late night: "Why is this a good idea?" Watch his response below.
"I'll tell you what I'm worried about mostly is, let's say I have to go out some place—where am I going to get a suit?" Letterman wondered.
To top everything off, Seinfeld also performed his original stand-up routine from his first appearance on Late Night with David Letterman.
